SF mod note SE corner of map is inaccurate : 1. There is no miltary base at location shown as Al-KIBAR, just derelict building bombed by Israelis in 2007 (see Wiki entry : Operation Orchard, now mysteriously re-written !) and 2. The main N4 highway Raqqa-Deir ez-Zour does not run alongside the Euphrates riverbank here but runs in a direct line from Ma’din al Jadid to Al Tibni,( 25 air km) thus bypassing the basalt high ground and narrow channel. There is an imperative bridge crossing (just 180 m wide) north of the historic Roman fortress excavations. Hope this helps, SDF have NOT taken a “large military base “, contrary to earlier reports, to my knowledge.
